Fuse box diagram (fuse layout), location, and assignment of fuses and relays Volkswagen Golf Mk5 (1K) (2003, 2004, 2005, 2006, 2007, 2008, 2009).
Checking and Replacing Fuses
The fuses are designed to blow before the entire wiring harness is damaged. If any of the electrical components do not operate, a fuse may have blown. If this happens, check and replace the fuses as necessary.
- Switch off the headlights, the ignition, and all electrical consumers.
- Open the appropriate fuse box.
- See diagrams below for details about which fuse to check.
- Remove the fuse using the plastic tweezers located on the fuse box cover.
- Check if the fuse is blown – if the thin metal strip inside is broken, the fuse has blown.
- If the fuse is blown, replace the fuse with a new fuse of the same amperage (same color and same imprint) and the same overall size.
- Replace the cover.
Notice
- Never replace a fuse with one that has a higher amp rating. Replace a blown fuse only with a fuse of the same amperage (same color and same imprint) and the same overall size.
- Never repair fuses.
- Never replace fuses with a metal strip, a paper clip, or a similar object.
- If a newly replaced fuse blows again after a short time, the electrical system should be checked by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
Location
- Engine compartment fuse box
- Relay carrier on the onboard supply control unit (left under dash panel)
- The instrument panel fuse panel
- Additional relay carrier, under a box in the engine compartment
Instrument Panel Fuse Box
The fuse panel is located behind the cover on the driver’s side of the dashboard. Remove the cover.
